In this paper an attempt is made to treat the impacts of nucleons very high energy (\ensuremath{\gg} ${\mathrm{Mc}}^{2}$). These lead meson emission, despite relatively small momentum transfers be expected, because changes nuclear charge and spin require a readjustment fields. Where fields are strong (as e.g., in pseudoscalar case), emission multiple, multiplicity increases with energy. For weaker coupling (e.g., scalar fields) not true. Two closely related methods developed for more...

A phenomenological treatment of charged and neutral photomeson production from deuterons is presented which independent the details meson theory. It shown that an experimental comparison deuteron proton cross sections can be used to determine nucleon spin flip probability.

In the early morning of April 26, 1986, as culmination an almost incredible series errors that began 24 hours earlier, Unit 4 Chernobyl nuclear complex, a so-called RBMK-1000 reactor, suffered worst accident in history commercial power. There was uncontrolled excursion, release large amount energy, possibly comparable to hundreds pounds TNT, blowing top off reactor. no containment, traditional American sense, so roof building blown out, unprecedented radioactivity released biosphere, and...

The Risk Assessment Review Group was organized by the U.S. Nuclear Regulatory Commission on July 1, 1977, with four elements to its charter: (1) Clarify achievements and limitations of WASH-1400, "Rasmussen Report." (2) Assess peer comments thereon, responses those comments. (3) Study present state such risk assessment methodology. (4) Recommend how (and whether) methodology can be used in regulatory licensing process.

The validity of the gaussian approximation for range straggling, due to ionization and excitation, a nonrelativistic charged heavy particle is investigated. Exact solutions are obtained which show that, in comparison with usual theory: (a) mean slightly increased; (b) distribution has tail direction shorter-than-average range; (c) most probable longer than range. First fictitious problem solved, then transition real world made.
